Anyone's perception is $5 is affected by their economic class. Globally, there are a significant number of people who would view $5 the same way others view .50.

For me, .15 a day is negligible. I can easily imagine someone who creates memes for social media choosing to pay that, especially if they feel there is value in supporting the creator. Memes aren't frivolity any more than other content - they're one of the most popular forms of communication on the internet.
